When effected by deed executed abroad, transfers of holdings in legal entities with a preponderance of real estate assets as defined in 2° of I of Article 726 are subject to registration duty under the conditions set out in this article, unless a tax credit equal to the amount of registration duty actually paid in the State of registration of each of the legal entities concerned is deducted, in accordance with the legislation of that State and in the context of a compulsory registration formality for each of these transfers. This tax credit can be offset against the French tax relating to each of these transfers, up to the limit of that tax.
